What fields does a Manifest file contain?
Core fields: name, short_name, start_url, display, icons, background_color, theme_color. Optional: description, orientation, scope, categories, screenshots, etc.
What display modes are available?
Four modes: standalone (independent app, no browser UI), fullscreen (no UI at all), minimal-ui (basic navigation buttons), browser (normal browser tab). Standalone is recommended for best PWA experience.
